This is the Groom Lake security helicopter photographed at basecamp.
The image was tweaked quite a bit so that the tail number can be seen.
Photo taken 9/17/2007.

Since you have no responses to your latest posting, I thought I should 
let you know there is at least one person who appreciates them.  I live 
in New England without as much chance of visiting Nevada as hitting the 
lottery so I have to I have to learn about Area 51 vicariously through 
postings like yours.  Thanks.
